This is my feel as well, I have to maintain a somewhat complex custom SSR, and each update of react-router has been a pain, basically when they moved from using regex URLs to simpler paths, it was a reasonable decision, but the docs of the new supported patters were lacking, newer docs versions are barely searchable, or directly you won't find mentions to some existing APIs anywhere.

I tried their "get started" project with the newly typed routes, and it feels too complex, and unintuitive, the purpose of a framework is to make your life easier, and it's sad to see people with this much talent missing the goal, I won't be using react-router for future projects.
